So basically other than the cool tweaks...current TDM based HD people have no major (sonic) reasons to upgrade just the software? for 1k?
The hardware must be upgraded to take advantage of the float?
So really my options are go big and get an HDX bundle with new i/o (trading in my HD|2 accel)
<OR>
get a HD Native card (on the upgrade path) and keep my current 192?
<OR>
go back to regular pro tools land (find some i/o) but enjoy the float?
